Tips: No trainer should be without a Geodude (it eventually evolves into Golem -- which gets my vote for best Ground Pokémon). Like all Rock Pokémon, Geodude is a dual type. Rock is great against Fire, Ice, Flying and Bug Pokémon, but it also adds a few weaknesses to Geodude's Ground abilities. You just need to know which types to stay away from and you'll be fine. Sadly, there are only two Rock techniques in Blue, Red or Yellow -- Rock Throw (decent) and Rock Slide (good). While Geodude doesn't learn Rock Slide on its own you can (and should) use TM 48 to teach it this powerful technique. Many Ground Pokémon are helpless when facing a Flying type (Ground techniques can't hit Flying Pokémon), but thanks to Geodude's Rock attacks, you can instantly squash any Flying opposition. On the other hand, moves like Earthquake and Dig are super-effective against Fire, Electric, Poison and even fellow Rock types. But Geodude's meanest and certainly most effective technique is Self Destruct (which you should later replace with Explosion). Though it causes your Pokémon to faint instantly, it helps you knock out even the strongest opponents. Use Explosion when your Geodude is low on HP or when you're battling a friend who relies heavily on Mewtwo or similar super-stars. A good lineup of moves for Geodude would be: Rock Slide, Dig, Fire Blast and Explosion. Fire Blast can come in very handy when facing Grass types. Alternative choices include Rest, Strength, Seismic Toss (for high-level Pokémon) or any powerful physical attacks.

In battle, use Rock Slide or Rock Throw against Fire, Ice, Flying or Bug Pokemon. If you're facing Electric, Poison or Rock opponents, use Dig, Earthquake or similar Ground attacks (you can also use them against Fire types to great effect). Geodude should be your Pokémon of choice against Electric types, but it's also great against Poison, Rock, Normal, Flying and Fire Pokémon. When fighting against Geodude, your #1 choice would of course be a Water type. Grass types also work well (but beware of Geodudes that know Fire Blast), as do Fighting and fellow Ground Pokémon. Ice Pokémon are a gamble. Though their techniques cause a lot of damage, Ice types are very weak to Rock attacks. Stick with Water techniques like Surf or Hydro Pump. They never fail to wash away Ground and Rock/Ground types.
